A few days ago, several members remarked about metal in their rear diffs after short mileage. As a caution, I had mine changed today. The report was that there was metal, but not a large amount, but that the fluid was unusually dirty, and it was good that it was changed. I trust these guys, not a dealer, and they don't steer you wrong. V6, Auto, 5,700 miles, very easily driven.

I bought Mobil 1 and also the FM. Paid the dealer to change it and watched them do it. They also showed me all the metal and crappy fluid that came out after 5700 miles. Now there is a record that it was done in case of warranty issues down the road.
